BACKGROUND OF THE INVENTION

There are mobile communication devices known which contain memory devices having unique memory device identifications, e.g. the MIFARE® classic family, developed by NXP Semiconductors, a contactless smart card IC operating in the 13.56 MHz frequency range with read/write capability. Recently, secure memory elements have been developed which are memory devices providing enhanced security features, particularly for the use in mobile phones and other mobile communication devices with Near Field Communication (NFC) capabilities. Said secure memory elements are also known as “Smart Cards”. One of the leading representatives of these secure memory elements is the SmartMX (Memory eXtension) smart card family that has been designed by NXP Semiconductors for high-security smart card applications requiring highly reliable solutions, with or without multiple interface options. Key applications are e-government, banking/finance, mobile communications and advanced public transportation. SmartMX architecture combines coprocessors for RSA, ECC, DES and AES and enables implementation of operating systems including Java Open Platform and MULTOS. The ability of SmartMX cards to run the MIFARE protocol concurrently with other contactless transmission protocols implemented by the User Operating System enables the combination of new services and existing applications based on MIFARE (e.g. ticketing) on a single Dual Interface controller based smart card. SmartMX cards are able to emulate MIFARE Classic devices and thereby makes this interface compatible with any installed MIFARE Classic infrastructure. The contactless interface can be used to communicate via any protocol, particularly the MIFARE protocol and self defined contactless transmission protocols. SmartMX enables the easy implementation of state-of-the-art operating systems and open platform solutions including JCOP (the Java Card Operating System) and offers an optimized feature set together with the highest levels of security.

Service Providers like banks, public transport companies, loyalty programs owners etc. provide contactless services to customers who are defined as persons using the mobile communication devices, e.g. NFC mobile phones, for mobile communications and contactless services. These contactless services comprise the provision of transport passes, cinema tickets, coupons, etc. which can be subsumed by the generic terms “applications” and “services”. In the following description the term “application” will be used which has to be understood in a broad sense.

A customer buys applications for instance by ordering them from the website of a Service Provider. In the course of the purchasing procedure the customer inputs a unique identification number of his/her communication device, e.g. the telephone number of a NFC mobile phone, so that the Service Provider knows unambiguously where to send the application.

Then the Service Provider transmits the application to the customer's mobile communication device via any communication channel, e.g. the Over The Air (OTA) transport services of a Mobile Network Operator to which the customer is subscribed. Alternatively, the Service Provider communicates indirectly with the mobile communication device via a Trusted Service Manager which securely distributes and manages the Service Provider's applications and transmits them to the mobile communication device. The Trusted Service Manager does not participate in the transaction stage of the applications, thus ensuring that the Service Provider's business models are not disrupted. Trusted Service Managers can be managed by one or a plurality of Mobile Network Operators, or by independent Trusted Third Parties.

When the applications are received by the mobile communication device they are stored in a secure memory element of the mobile communication device and can be consumed by the customer by positioning the mobile communication device within the range of transmission of a reading device which reads and processes the application in an appropriate manner, e.g. by giving the user access to an entrance of a concert hall. After the applications have been consumed or expired they have to be deleted from the memory element in order to free memory space for future applications.

However, deleting the expired applications from the memory element is problematic if the customer wants to keep a trace (could be a receipt) of the applications that he/she has consumed. The same problem arises if the customer wants to acquire a collector object from the applications consumed (for instance if the applications corresponds to a concert ticket).

OBJECT AND SUMMARY OF THE INVENTION

It is an object of the invention to provide a mechanism that enables the customer to keep applications that have been consumed or expired or representations of them and yet to delete the applications from the memory element of his/her mobile communication device.

In order to achieve the object defined above, with a method according to the invention characteristic features are provided so that a method according to the invention can be characterized in the way defined below, that is:

A method for managing expired or consumed applications that have been provided by a Service Provider and are stored in a memory element of a mobile communication device, e.g. a NFC mobile phone, wherein the method comprises storing a representation of expired or consumed applications in or on a storage medium that is separate from the memory element.

FIG. 2 and FIG. 3 show schematic flow charts of a first embodiment of a method for managing expired or consumed applications according to the present invention.

FIG. 4 shows a schematic flow charts of a second embodiment of a method for managing expired or consumed applications according to the present invention.

DESCRIPTION OF EMBODIMENTS

FIG. 1 shows a schematic diagram of a system for providing contactless services to mobile communication devices MOB. The system comprises a Service Provider SP (it should be noted that the number of Service Providers is not limited), a Mobile Network Operator MNO providing the full range mobile services, particularly UICC and NFC terminals plus Over The Air (OTA) transport services, and a mobile communication device MOB representing an unlimited number of mobile communication devices. The mobile communication device MOB belongs to a customer CS who is a subscriber of the Mobile Network Operator MNO. Let us assume that over the time the customer has ordered a number of NFC (Near Field Communication) applications app1, app2 . . . appx, e.g tickets, transport passes and so on. The Service Provider SP has transmitted the applications app1, app2 . . . appx either directly to the customer's mobile communication device MOB via the Over The Air transport services of the Mobile Network Operator MNO, or indirectly by sending them to a Trusted Service Manager TSM which then has forwarded the applications app1, app2 . . . appx to the mobile communication device MOB via the Over The Air transport services of the Mobile Network Operator MNO. The Service Provider SP communicates with the Trusted Service Manager TSM via a computer network, such as the Internet, wherein the preferred data transmission protocol is HTTPS.

Additionally or alternatively, the Service Provider SP communicates with the mobile communication device MOB via a computer network and wireless services, e.g. NFC reading devices RD.

The mobile communication device MOB may e.g. be configured as a NFC mobile phone. The mobile communication device MOB comprises a secure memory element SE which is a memory device with enhanced security features, such as for instance a MIFARE device or a smart card like a SmartMX device. The mobile communication device MOB further comprises a service manager SM that is implemented as a computer program and is configured to manage the received applications app1, app2 . . . appx, particularly to install them in the secure memory element SE and to delete them, if necessary. The customer CS consumes or uses the stored applications app1, app2 . . . appx by positioning the mobile communication device MOB within the range of the reading device RD which reads and processes the applications in an appropriate manner, e.g. when one application is a transport pass by giving the customer CS access to a public transport system and at the same time reducing the number of remaining public transport tickets by one. In the end, making use of the applications app1, app2 . . . appx results in consumed or expired applications that should be deleted from the secure memory element SE in order to free memory space for other applications.

For the following explanations, let us assume that the application app2 has expired and shall be deleted from the secure memory element SE as shown in the schematic block diagram of FIG. 2. At the time when the application app2 has to be deleted the consumer CS chooses to keep the application app2. Alternatively he could also choose to keep a representation thereof. The consumer CS inputs a collecting request CL into his mobile communication device MOB, e.g. by pressing a combination of keys. The service manager SM in the mobile communication device MOB receives the collecting request CL and handles it by reading the application app2 from the secure memory element SE and storing a copy thereof in a collector memory MM separate from the secure memory element SE. The collector memory MM is either a dedicated memory element such as a memory card inserted into the mobile communication device MOB or an internal memory of the mobile communication device. When copying of the application app2 to the collector memory MM has successfully been completed the service manager SM deletes the expired or consumed application app2 from the secure memory element SE. In other words, the service manager SM handles the customer's CM collecting request CL by moving the application app2 from the secure memory element SE to the collector memory MM. The final state of this operation is shown in FIG. 3. It should be noted that deleting the application app2 from the secure memory element SE can be carried out by the service manager either automatically or upon a specific deleting request of the customer CS.

With reference to FIG. 3 a second embodiment of the invention will be explained now. Again, it is assumed that the application app2 has expired and shall be deleted from the secure memory element SE. The consumer CS chooses to keep a representation of the application app2. He inputs a collecting request CL into his mobile communication device MOB, e.g. by pressing a combination of keys. The service manager SM in the mobile communication device MOB receives the collecting request CL and handles it by connecting to the Service Provider SP, for instance via a wireless Internet connection, and sending a retrieval request RTR to the Service Provider SP asking the Service Provider SP to retrieve the application app2 from its application data base DB and to make it available for the customer CS in a format that has been chosen by the customer CS when inputting the collecting request CL. The chosen format can for instance be selected from the application app2 itself provided in a binary format, an electronic document containing specific information of the application app2 like the price, the name, a release number, a receipt, a characteristic image and so on, or a human-readable format, e.g by printing it on a printable substrate like a sheet of paper. After the Service Provider SP has formatted the representation RP of the application app2 as requested it transmits it to the customer CS via any suitable communication channel, e.g. via e-mail, or download from a remote server, or mail transport, etc.

After the service manager SE has sent the retrieval request RTR to the Service Provider SP it will delete the expired or consumed application app2 from the secure memory element SE. Deleting the application app2 from the secure memory element SE can be carried out by the service manager SM either automatically or upon a specific deleting request of the customer CS.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word “comprising” does not exclude the presence of elements or steps other than those listed in a claim.
